SPECIFICATION forming part of Lettere Patent No. 637,215, dated November 14, 1895.

Application filed May 8, 1899. Serial No. 716,006. (No model.)

To all toil/0m it may concern:

Beit known that I, JULIAN H. PITKIN, acitizen of the United States, residing at Ravenstvood, in the county of Cook and State of Illinois, have invented certain new and useful Improvements in Sheaf-Carriers; and I do hereby declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same.

The invention has for its object to provide an improved form of carrier for the bundles of grain that are bound by self-binding harvesters, and has particularly in view to provide a carrier for corn-binders of a now Wellknown type.

For the purpose of making the parts forming the subject-matter of my invention easily distinguishable from those of the machine to which it is attached I have shown the latter mainly in dotted lines.

Figure l is a perspectiveview of my invention as seen from a point forward of the machine and a little stubbleward. Fig. 2 is a perspective viewvin detail of the trippingpedal as seen from the saine point of View. Fig. 3 represents the same parts as seen from a point stubbleward and in rear of the main supporting-wheel. In this the binding-table, the stubble edge of which cooperates with the sustaining-ngers, is shown in full lines.A

Fig. et is a plan view of the tripping mechanism.

My invention is particularly adapted to a Well-known form of corn-binder or to any kind of grain-binding machine in which the bundles are delivered in the rear of the main supporting-Wheel.

A4 is the main supporting-wheel, and the parts lettered B represent parts of the main framework. Upon this framework are secured the seat-spring and the seat for the attendant.

The bundle-carrier consists of the rockshaft C, sustained inthe supports C and C2, the curved carrier-fingers e being secured to the rock-shaft C by passing therethrough and taking nuts. When in Working position, the partsof the carrier are as shown in Fig. 3, the fingers extending well toward the binding- Firmly secured upon the rock-shaft C is the crank-arm D. -Upon the Wrist of this crank-arm is supported the trip-lever E. To the inain frame B is secured the pivot-piece F. To this atfthe arm G is pivoted. This arrn and the stubble end of the trip-lever E are pivoted together by the pin g. Around this pin is secured the spring g', one end being hooked under the trip-lever E and the other under the arm G. The purpose of this spring is to bring the parts G and E to the position shown in Figs. l and 3 and form a toggle-lock to hold the carrier in receiving position. On the arm G is the stop g2, adapted to strike Vthe lever E, as shown in Figs. l, 3, and' 4.

The purpose of so securing the lever is twofold: First, when in the position shown in Fig. 3 the parts G and D are as one piece in that the pivots being in line the bundle-carrier is held in the receiving position, as by a simple connection; but when the knee-joint, `formed as shown, is broken by pressure upon the end of the trip-lever E the bundle-carrier iingers are free to move away from the bindingtable under the weight of their load and permit the latter to fall to the ground. The tension of the spring g should be sufficient to bring the lock-lever to its normal position, and thus return to and sustain the carrier in position to receive a new load. Upon the stubble edge of the binding-table I are the iingers H, pivoted to the table at h, as shown in Fig. 3. They serve to guide the bundles outward onto the teeth of the carrier as discharged from the binding-receptacle, as well as to impart support to the bundles, and their pivotal connection with the table allows them to draw from beneath the bundles as the machine advances. As the bundle-carrier fingers are moved outward in dumping the larger portion of the load falls to the ground and one or more bundles thatv lie partly on the teeth H are readily dropped by the action of the teeth H, which swing backward and draw from beneath.

The operation is as follows: Vith the parts in the position shown in Fig. l, the load of bundles resting mainly upon the fingers e and the leverE and connection G in the position shown in Fig. 1, the said parts last- Inentioned serve as a sti bar in that the arm D, and hence the rock-shaft, is not permitted IOO to move. If, however, the operator presses upon the end of the lever E, the knee-joint formed by the said lever and the arm G is broken, and the Weight of the load is thus set free to cause the shaft to rock and permit the bundles to fall. The springg serves to return the parts to position (shown in Fig. 1) when the foot is removed.

What I claim is- 1. In a bundle-carrier for harvesters, the Acombination of a rock shaft provided with ingers adapted to receive and hold the bundles, said rock-shaft supported upon the main frame and having an arm D, a trip-lever pivotally connected With said arm, one end of said lever being adapted to receive pressure, and the other end being sustained upon the mainframe in such a manner that it can move endwise and permit movement of the rockshaft.

2. In a bundle-carrier for harvesters, the combination of a rock-shaft provided with ngers adapted to receive and sustain the bundles, said rock-shaft being suitably supported upon the main frame and having a crank-arm D, a trip-lever E pivotally connected. With said crank-arm, one end of said lever being connected to the main frame by the pivoted arm G, and said two arms E and G being suitably pivoted together and provided at their joints with the spring g'.

3. In a bundle-carrier for harvesters, the combination of a rock-shaft having a crankarm, a trip-lever E supported upon the Wrist of the said crank-arm, linked at one end by a pivoted arm G to the main frame, said arm and lever being pivoted together, the spring g', and stop g2 to hold the said lever and arm in such a position as to form a straight connection between the main frame and the crankarm D, and thus maintain the position of the sheaf-carrier when receiving its load.

4. The combination with the binding-table of a harvester, of the fingers H projecting outwardly therefrom, the rock-shaft C provided With lingers projecting toward the fingers H and journaled in bearings above the table and having au operating crank-arm D, a lever E pivotally connected between its ends to said crank-arm, said lever having one end free and the other connected by means of a pivoted arm to a ixed part of the machine.
